System and method to manage server configuration profiles in a data center

ABSTRACT

An information handling system includes first and second data processing systems and a configuration management system. The configuration management system determines to change a first configuration setting for the first data processing system, modifies a first configuration profile for the first data processing system to include the changed first configuration setting, determines that the change to a first configuration setting necessitates the change to a second configuration setting for the second data processing system, modifies a second configuration profile for the second data processing system to include the changed second configuration setting, exports the modified second configuration profile to the second data processing system, and exports the modified first configuration profile to the first data processing system after exporting the modified second configuration profile to the second data processing system.

FIELD OF THE DISCLOSURE

This disclosure generally relates to information handling systems, and more particularly relates to managing server configuration profiles in a data center.

BACKGROUND

As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option is an information handling system. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes. Because technology and information handling needs and requirements may vary between different applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software resources that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.

SUMMARY

An information handling system may include first and second data processing systems and a configuration management system. The configuration management system may determine to change a first configuration setting for the first data processing system, modify a first configuration profile for the first data processing system to include the changed first configuration setting, determine that the change to a first configuration setting necessitates a change to a second configuration setting for the second data processing system, modify a second configuration profile for the second data processing system to include the changed second configuration setting, export the modified second configuration profile to the second data processing system, and export the modified first configuration profile to the first data processing system after exporting the modified second configuration profile to the second data processing system.

DETAILED DESCRIPTION OF DRAWINGS

The following description in combination with the Figures is provided to assist in understanding the teachings disclosed herein. The following discussion will focus on specific implementations and embodiments of the teachings. This focus is provided to assist in describing the teachings, and should not be interpreted as a limitation on the scope or applicability of the teachings. However, other teachings can certainly be used in this application. The teachings can also be used in other applications, and with several different types of architectures, such as distributed computing architectures, client/server architectures, or middleware server architectures and associated resources.

FIG. 1 illustrates an embodiment of a data center 100 including server aisle 110, and a data center management controller (DCMC) 160. Server aisle 110 includes server racks 110, 120, 130, 140, and 150. Server racks 120, 130, 140, and 150 include various equipment that operates to perform the data storage and processing functions of data center 100. As such, one or more elements of data center 100, including the equipment in server racks 120, 130, 140, and 150 and DCMC 160 can be realized as an information handling system. Each of server racks 110, 120, 130, 140, and 150 includes a respective rack management controller (RMC) 112, 122, 132, 142, and 152. RMCs 112, 122, 132, 142, and 152 represent service processors that operate in accordance with an Intelligent Platform Management Interface (IPMI) functional implementation to provide monitoring, management, and maintenance functionality to the respective server racks 110, 120, 130, 140, and 150, and to the equipment therein. Examples of RMCs 112, 122, 132, 142, and 152 can include service processors, such as baseboard management controllers (BMCs), an Integrated Dell Remote Access Controller (iDRAC), another service processor, or a combination thereof. RMCs 112, 122, 132, 142, and 152, and DCMC 160 are connected together with various service processors associated with the equipment in server racks 110, 120, 130, 140, and 150 into a management network whereby the DCMC can remotely manage the equipment in the server racks.

The equipment in server racks 110, 120, 130, 140, and 150 include stand-alone servers, blade servers, storage arrays, I/O and network switches and routers, power supplies, and the like, as needed or desired. Each element of server racks 110, 120, 130, 140, and 150 needs to be configured to operate within the overall processing environment of data center 100. The configuration of each element is particular to the function provided by the element, the physical and virtual locations of the elements on various data and storage networks of data center 100, the desired management and environmental parameters of the data center and the particular elements, BIOS or UEFI settings, and the like. In general, each element of server racks 110, 120, 130, 140, and 150 includes a management controller such as a Baseboard Management Controller, or the like, that permits DCMC 160 to manage the configurations of the elements of the server racks. While each manageable parameter of the elements of server racks 110, 120, 130, 140, and 150 may be individually managed, in practical fact, many of the manageable parameters of the elements of the server racks will have similar configuration settings as other similar elements of the server rack. For example, BIOS settings, such as system controller settings, system clock settings, system boot configurations and boot order, and the like may be the same for all stand-alone servers or blade servers of a particular type.

As such, the elements of server racks 110, 120, 130, 140, and 150 are each configured based upon a Server Configuration Profile (SCP). A SCP embodies the concept of performing server configuration through a single file. As such, a SCP can be generated in a XML or JSON format and can be exported to the elements of server racks 110, 120, 130, 140, and 150 with an Export Server Configuration operation. Configuration changes can be edited into the SCP and can be applied to one or more of the elements of server racks 110, 120, 130, 140, and 150 with an Import Server Configuration operation. Thus, as illustrated, server rack 110 is associated with a SCP 114, server rack 120 is associated with a SCP 124, server rack 130 is associated with a SCP 134, server rack 140 is associated with a SCP 144, and server rack 150 is associated with a SCP 154. However, as described further below, it will be understood that each element of server racks 110, 120, 130, 140, and 150 will include its own SCP, and thus each of SCPs 114, 124, 134, 144, and 154 are illustrative of several SCPs, one for each element of the associated server rack. DCMC 160 creates, maintains, and implements SCPs 162 for the various types of elements within server racks 110, 120, 130, 140, and 150. An example of configuration settings that can be set utilizing SCPs 114, 124, 134, 144, and 154 includes BIOS configuration settings, such as BIOS passwords, BIOS boot mode (e.g. PXE, Legacy, UEFI, etc.), time zones and real-time clock (RTC) settings, BIOS boot order, and other configuration settings that are configurable via a BIOS setup utility, network configuration settings, such as static IP addresses, network adapter partitions, VLANs, and other network configuration settings, storage configuration settings such as RAID configuration settings, boot image locations, virtual drive settings, and other network configuration settings, management network settings such as management VLANs, environmental alarm limits, power limits and other management network settings, as needed or desired.

FIG. 2 illustrates a server rack 200 typical of server racks 110, 120, 130, 140, and 150. Server rack 200 includes a rack space that represents a standard server rack, such as a 19-inch rack equipment mounting frame or a 23-inch rack equipment mounting frame, and includes six rack units. The rack units represent special divisions of the rack space that are a standardized unit of, for example, 1.75 inches high. For example, a piece of equipment that will fit into one of the rack units shall herein be referred to as a 1-U piece of equipment, another piece of equipment that takes up two of the rack units is commonly referred to as a 2-U piece of equipment, and so forth. As such, the rack units are numbered sequentially from the bottom to the top as 1U, 2U, 3U, 4U, 5U, and 6U. The skilled artisan will recognize that other configurations for rack units can be utilized, and that a greater or lesser number of rack units in a server rack may be utilized, as needed or desired. For example, a rack unit can be defined by the Electronic Components Industry Association standards council.

Server rack 200 further includes a rack management controller 210 and a rack management switch 220, and is illustrated as being populated with two 2-U servers 230 and 240, and with two 1-U storage arrays 250 and 260. 2-U server 230 is installed in rack spaces 1U and 2U, 2-U server 240 is installed in rack spaces 3U and 4U, 1-U storage array 250 is installed in rack space 5U, and 1-U storage array 260 is installed in rack space 6U. Rack management controller 210 includes network connections 212 and 214, and rack switch 220 includes network connections 222, 223, 224, 225, and 226. As illustrated, rack management controller 210 is connected via network connection 214 to a management network that includes a DCMC 280 similar to DCMC 160, and is connected via network connection 212 to network connection 222 of rack switch 220 to extend the management network to servers 230 and 240, and to storage arrays 250 and 260. As such, server 230 includes a BMC 231 that is connected to network connection 223 via a network connection 232, server 240 includes a BMC 241 that is connected to network connection 224 via a network connection 242, storage array 250 includes a BMC 251 that is connected to network connection 225 via a network connection 252, and storage array 260 includes a BMC 261 that is connected to network connection 226 via a network connection 262. Here, the management network includes RMC 210, BMCs 231, 241, 251, and 261, and DCMC 280. DCMC 280 is configured to initiate management transactions with RMC 210 to monitor, manage, and maintain elements of server rack 200, of management switch 220, of servers 230 and 240, and of storage arrays 250, and 260 via respective BMCs 321, 241, 251, and 261.

BMC 231 operates to monitor, manage, and maintain server 230. In monitoring server 230, BMC 231 accesses various sensors for monitoring various physical characteristics of the server, such as temperature sensors, fan speed sensors, voltage sensors on the various voltage rails, current sensors on the voltage rails, humidity sensors, and the like, to characterize the environmental conditions within which the server is operating. BMC 231 further accesses various state information of the elements of server 230, such as by accessing I/O state information related to the operating condition of the elements of the server, and the like, to further characterize the environmental conditions within the elements of the server. BMC 231 further accesses various software and firmware information, such as processor loading information, memory and storage utilization information, network and I/O bandwidth information, and the like, to characterize the processing conditions of server 230. BMC 231 further operates to provide the monitoring information to RMC 210 and to DCMC 280 via the management network, as needed or desired.

In managing server 230, BMC 231 utilizes the monitoring information from the server to provide inputs to control various physical operations of the server, such as fan speeds, voltage levels, processor clock rates, I/O speeds, and the like, to ensure that the environmental conditions of the server and the elements thereof remain within acceptable limits. BMC 231 further operates to provide indications as to the environmental and processing conditions to RMC 210 and DCMC 280, as needed or desired. For example, when temperature conditions within server 230 exceed a particular threshold, then BMC 231 can provide a high-temp indication to that effect to RMC 210 and the RMC can direct a heating/ventilation/air conditioning (HVAC) system of the data center to direct additional cooling to server 230. Similarly, when temperature conditions within server 230 drop below another threshold, then BMC 231 can provide a low-temp indication to that effect to RMC 210 and the RMC can direct the HVAC system to direct less cooling to server 230.

In managing server 230, BMC 231 further utilizes the monitoring information from the server to provide inputs to control various processing conditions of the server. For example, when processing conditions, such as processor loading or memory utilization, within server 230 exceed a particular threshold, then BMC 231 can provide a high-utilization indication to that effect to DCMC 280, and the DCMC can direct spare servers of the data center to come on line to offload the workload from the server. Similarly, when processing conditions within server 230 drop below another threshold, then BMC 231 can provide a low-utilization indication to that effect to DCMC 280 and the DCMC can direct initiate steps to shut down server 230 and place it into a pool of spare servers for the data center.

In maintaining server 230, BMC 231 operates to ensure that the operating thresholds, set points, and other limits are maintained, and to reset or change the thresholds, set points and other limits as needed or desired. Further, BMC 231 operates to maintain software and firmware in server 230, as needed or desired. BMCs 241, 251, and 261 operate to monitor, manage, and maintain respective servers 240, 250, and 260 similarly to the way that BMC 231 operates on server 230, as described above. Moreover, RMC 210 operates to monitor, manage, and maintain functions and features of server rack 200, as needed or desired. Further, RMC 210 operates as a central node of the management network between BMCs 231, 241, 251, and 261, and DCMC 280, colleting monitoring information from the BMCs and providing management and maintenance information to the BMCs, as needed or desired.

DCMC 280 includes a SCP manager 282 that operates to create, modify, and deploy SCPs for the elements of server rack 200. In particular, rack switch 220 includes a SCP 228, servers 230 and 240 include respective SCPs 238 and 248, and storage arrays 250 and 260 include respective SCPs 258 and 268. In general, SCP manager 282 can create, modify, and deploy SCPs 228, 238, 248, 258, and 268 separately and as needed or desired. For example, if it is determined that server 230 needs a new configuration setting applied, SCP manager 282 operates to modify a copy of SCP 238 maintained at DCMC 280 and to deploy the modified SCP to the server. In some instances, SCP manager 282 deploys SCPs by directly communicating the SCPs to the elements of server rack 200 for the elements to apply to themselves, as needed of desired. For example, rack switch 220 may include an in-band mechanism, such as a management VLAN that permits the rack switch to receive management information and to deploy the management information to the rack switch. Here, SCP manager 282 can deploy SCP 228 via the in-band mechanism to rack switch 220, and the rack switch operates to make the modifications to its configuration as provided by the SCP. In other instances, SCP manger 282 deploys SCPs by communicating the SCPs to a management controller of the elements, and the management controller applies the SCPs to the associated elements. For example, server 230 includes BMC 231. Here, SCP manager 282 can deploy SCP 238 via an out-of-band transaction to BMC 231, and the BMC operates to make the modifications to the configuration of server 230 as provided by the SCP.

In a particular embodiment, SCP manager 282 does not create, modify, and deploy SCPs individually on the elements of server rack 200. Instead, SCP manager 282 maintains various operational SCP templates based upon different types or classes of elements within server rack 200 and within the data center that includes the server rack. For example, where elements of the data center are of a same type, such as where server racks are deployed with a common top-of-rack switch, or where a large number of blade servers of a particular model are deployed throughout the data center, SCP manager 282 can implement one operational SCP template for the top-of-rack switches and a different operational SCP template for the blade servers. This reflects the fact that it may be desirable to maintain many of the configuration settings within a particular type of equipment in common across all of the instances of that type of equipment. Thus by maintaining a smaller number of operational SCP templates, SCP manager 282 can more easily maintain the elements of the data center. For example, where a configuration setting that is common for a large number of the elements of the data center, such as a RTC setting, SCP manger 282 can make changes to the common setting in the smaller number of operational SCP templates and deploy the changes by exporting the templated SCPs across the data center. Then, only when a change effects only one element of the data center, such as a MAC or IP address, SCP manager can deploy changes to the individual SCPs as described above.

In a particular embodiment, in creating, modifying, and deploying SCPs, SCP manager 282 operates to maintain dependency information between the configuration settings in the operational SCP templates, and to deploy updated SCPs based upon the dependency information. For example, as noted above, many of the configuration settings for a particular type of equipment may be modified and deployed without reference to any other equipment in the data center. Consider a server, such as server 230. Changes to the RTC setting of the server may not depend upon, interfere with, or be interfered with by any other equipment in the data center. Thus the RTC setting of an operational SCP template for servers may indicate that changes to the RTC setting of servers is not dependent upon any other equipment of the data center. On the other hand, a change to the boot directory of a server may necessitate updating of one or more storage elements like storage arrays 250 and 260, before a next boot cycle of the server is performed, and so the operational SCP template for servers may indicate that changes to the boot directory of servers must be accompanied by the consequent changes to storage arrays prior to any system reboot of the servers. Further, a change to a VLAN of a server may cause unintended loss of data if the other elements that are associated with the modified VLAN setting are not modified before the server. For example, where RMC 210 and BMC 242 are to communicate with each other over a new VLAN, it may be necessary to first provide a modified SCP for rack switch 220, setting up the rack switch to accommodate the new VLAN, before either the RMC or server 240 are updated. Table 1, below, illustrates an example of an operational SCP template for server equipment in a data center. It will be understood that, for some modifications to an operational SCP template, there will be multiple overlapping, and possibly conflicting dependencies. As such, an operational SCP template may further specify a priority of action for the dependency actions, as needed or desired.

FIG. 3 illustrates a method for applying operational SCP templates in a data center, starting at block 300. Configuration setting changes to an operational SCP template are determined in block 302. The changes are evaluated with reference to the operations SCP template to identify the dependencies that are created by the configuration setting changes in block 304. The change with the most dependencies to resolve is selected and the identified prior activities and modifications are performed on the identified equipment in block 306. Note that here, the mitigation of one or more dependency may need to be resolved by the modification of one or more other operational SCP templates or individual SCPs, as needed or desired. A decision is made as to whether or not the resolved dependency is the last unresolved dependency in decision block 308. If not, the “NO” branch of decision block 308 is taken and the method returns to block 306 where the change with the next most dependencies to resolve is selected and the identified prior activities and modifications are performed on the identified equipment. If the resolved dependency is the last unresolved dependency, the “YES” branch of decision block 308 is taken, the operational SCP template is applied to the identified equipment in block 310, and the method ends in block 312.

In a particular embodiment, BMC 231 includes a configuration manager 232 that operates to maintain the configuration options of server 230, to determine when changes are made within the server, to determine from SCP manager 282 whether or not there are any dependencies related to the changes, and to take steps to mitigate the dependencies on server 230. Note that configuration manger 232, as illustrated, is local to server 230, but this is not necessarily so, and the functions and features of the configuration manager, as described below, may be applied equally to other equipment of data center 200, as needed or desired. Here, in addition to providing SCP 238 to BMC 231, SCP manager 282 also provides, on an as needed basis, a remediation policy to the BMC. The remediation policy can be provided as a file that includes the dependency information from the operational SCP template for server 230, such that configuration manager 232 can determine when a configuration setting change involves any dependencies.

Here, when configuration manager 232 detects a change to the configuration options of server 230, the configuration manager provides a request to SCP manger 282 over the management network to request the remediation policy information. Then configuration manger 232 determines if the configuration change involves any dependencies. If so, then configuration manager 232 operates to implement the remediation steps associated with the dependencies, if the dependencies implicate configuration settings within server 230. If the identified dependencies are outside of server 230, and therefore beyond the ability of configuration manager 232 to remedy, then the configuration manager sends a request to SCP manager 282 indicating that the configuration manager intends to perform the configuration change, and requesting the SCP manger to perform the remedial actions on the other elements of data center 200, as indicated by the remediation policy information. Here, configuration manager 232 can hold the requested configuration change from being implemented until SCP manager 282 indicates that the remediation actions have been performed. Then configuration manager 232 performs the requested configuration change.

In this way, the amount of management network traffic is reduced because BMC 231 initiates action only when a configuration setting is requested to be changed. Otherwise, SPC manger 282 would be required to poll all the elements of the data center to ensure that all requested configuration changes are evaluated for potential dependencies, thus consuming an increased amount of the processing resources on the management network. In a particular embodiment, when configuration manager 232 detects a configuration change request and requests the remediation policy information from SCP manger 282, the SCP manager provides the full remediation policy for server 230. In this way, configuration manager 232 has access to all of the dependency mitigation actions, and, on the assumption that one configuration change will be rapidly followed by other configuration change request, will not need to re-download the remediation policy information. In another embodiment, when configuration manager 232 detects a configuration change request and requests the remediation policy information from SCP manger 282, the SCP manager provides only the remediation policy information related to the requested configuration change.

FIG. 4 illustrates a method for applying configuration setting changes in a data center, starting at block 400. A request to change a configuration setting of an element of a data center is detected in block 402. Here, the element to be changed has detected the change request. The element that detected the change request issues a request to a DCMC to receive a remediation policy related to the change request in block 404. The DCMC determines whether or not the requested change has any dependencies based upon the operational SCP template and provides a remediation policy in block 406. A decision is made by the element of the data center as to whether or not the remediation policy received from the DCMC indicates any dependencies related to the detected configuration setting change request in decision block 408. If not, the “NO” branch of decision block 408 is taken, the requested configuration setting is changed in block 414, and the method ends in block 416. If the remediation policy received from the DCMC indicates dependencies related to the detected configuration setting change request, the “YES” branch of decision block 408 is taken and the element of the data center requests the DCMC to perform any mitigations associated with the requested change on other elements of the data center in block 410. A decision is made as to whether or not the dependencies have been mitigated in decision block 412. If not, the “NO” branch of decision block 412 is taken and the method returns to decision block 412 until the dependencies have been mitigated. When the dependencies have been mitigated, the “YES branch of decision block 412 is taken, the requested configuration setting is changed in block 414, and the method ends in block 416.

In another embodiment, server 240 includes a host-to-management pass through 244 and BMC 241 includes a configuration manager 242 similar to configuration manager 232. Host-to-management pass through 244 represents an in-band agent resident in a hosted environment of server 240 that communicates management information between the hosted environment of the server and the out-of-band environment of BMC 241. In particular, host-to-management pass through 244 operates to track the software and applications operating on the hosted environment and to determine the hardware resources that are utilized by the software and applications. Host-to-management pass through 244 then identifies the operating software and applications, along with the associated hardware resources utilized thereby, to configuration manger 242. Communication manager 242 operates to maintain the configuration options of server 240, to determine when changes are made to the configuration settings of the server, and to determine whether the configuration setting changes impact the hardware resources of the operating software and applications on the hosted environment of the server. Note that configuration manger 242 and host-to-management pass through 244, as illustrated, are local to server 240, but this is not necessarily so, and the functions and features of the configuration manager and the host-to-management pass through, as described below, may be applied equally to other equipment of data center 200, as needed or desired. When configuration manger 242 determines that a configuration setting change will impact the hardware resources of the operating software and applications on the hosted environment of server 240, the configuration manager operates to provide a warning that the proposed configuration setting changes may adversely impact the operation of the operating software and applications. Such a warning can be provided to a user of server 240, or to DCMC 280 via the management network, as needed or desired. In addition to the warning, configuration manager 242 operates to prevent the proposed configuration changes until an authorization for such changes is received by the configuration manager, such as from the user or from DCMC 280, as needed or desired.

FIG. 5 illustrates a method for assessing configuration changes on applications running in a server, starting at block 500. An in-band agent, such as a host-to-management pass through, detects the operating software and applications in the hosted environment of a particular piece of equipment in a data center in block 502. The in-band agent correlates the operating software and applications with the hardware resources utilized thereby in block 504. The in-band agent communicates information related to the operating software and applications and the associated hardware resources to a management controller of an out-of-band environment of the piece of equipment in block 506. A decision is made by the management controller as to whether or not a configuration setting change has been requested in decision block 508. If not, the “NO” branch of decision block 508 is taken and the method loops to decision block 508 until a configuration setting change has been requested. After a configuration change has been requested, the “YES” branch of decision block 508 is taken and a decision is made as to whether or not the configuration setting change is associated with a hardware resource dependency in decision block 510. If not, the “NO” branch of decision block 510 is taken, the configuration setting is changed in block 512, and the method ends in block 514. If the configuration setting change is associated with a hardware resource dependency, the “YES” branch of decision block 510 is taken, the management controller provides an warning that the pending configuration setting change is associated with a hardware resource dependency and halts execution of the configuration setting change in block 516, and the method ends in block 514.

FIG. 6 illustrates a generalized embodiment of information handling system 600. For purpose of this disclosure information handling system 600 can include any instrumentality or aggregate of instrumentalities operable to compute, classify, process, transmit, receive, retrieve, originate, switch, store, display, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, entertainment, or other purposes. For example, information handling system 600 can be a personal computer, a laptop computer, a smart phone, a tablet device or other consumer electronic device, a network server, a network storage device, a switch router or other network communication device, or any other suitable device and may vary in size, shape, performance, functionality, and price.
